Lots of anomalies with Marli.
I'll see if I can think of them all -
1. She didn't die.
2. In his initial statement Henri never mentioned seeing her as he first left the bedroom to run down the stairs, yet his bedroom light was on (and the parent's bedroom light was on), casting light onto the landing.
3. No spatter on Henri.
4. No dna in the shower.
5. No blood on the axe.
I think it's important that he didn't mention seeing Marli at that stage in his first statement, but did in his plea explanation. At the police station he didn't know if Marli would recover, and tell a different story to him. By the time of his plea statement he knows Marli has amnesia.
I think it was said they had to move Teresa to rescue Marli, so were they entangled to some extent? If Teresa went down first, why would Marli be under any part of her? I don't think they would have moved Teresa unless it was absolutely necessary. There could be another explanation like Teresa was blocking their ability to stand next to Marli, and not on top of Marli. I would like to have heard if Marli's blood spatter was on top of Teresa - maybe it's there and I've missed it.
I'm going to rack my brains to come up with a scenario for Marli. It may just be that her spatter direction was different, or Teresa or the wall next to the doorway were between Marli and Henri.
The other thing that's bothering me is Rudi's blood on the stair wall underneath the axe hole, and Henri's blood being on the axe handle -
a. If Rudi was attacked first his blood got on the axe first, and that axe was then used to attack at least Martin and Teresa, and in the most likely sequence, probably Marli. Rudi being the only donor of the blood on the wall beneath the axe hole, after two or three more attacks, is very unlikely.
b. Henri washed blood spatter off his skin. Galloway confirmed that there was no spatter on his body in the ambulance, yet we know there was lots of spatter on his shorts and socks. That's not how blood spatter behaves. Henri's wounds were created after his shower - the drips from them were evident, so had not been washed away when he washed off the family blood.
c. If Henri attacked everyone, showered, then cut himself and got blood on the axe handle (purposely), any of Rudi's blood left on the axe would have been minimal after it was swung around and used to attack the others and the blood would have started to dry on the axe by the time he had showered and cut himself.
I think it looks like he loaded up the axe with Rudi's blood again, to create a trail for the axe throwing stunt, because it would be obvious he'd done it some time later if the blood was dry and not still dripping.
I have a vague memory of thinking that they didn't take many swabs from the blood on the axe. Maybe they were slightly careless and assumed it would yield mixed results from all the victims, and when it didn't it was too late to retest it because it had been cleaned up. Who cleans a murder weapon before trial, and why?
Maybe he had to clean the axe blade before he put it into Rudi's blood because he thought it would be obvious fresh blood had been layered on top of dried blood.
I'm still thinking through the possibilities. Have a great day everyone, and massive thanks from me too, to JJ and Prime!
